JSON Server
Get a full fake REST API with zero coding
Get a full fake REST API with zero coding in less than 30 seconds (seriously). Created with <3 for front-end developers who need a quick back-end for prototyping and mocking. If you need to add authentication, validation, or any behavior, you can use the project as a module in combination with other Express middleware. You can deploy JSON Server. For example, JSONPlaceholder is an online fake API powered by JSON Server and running on Heroku. If you make POST, PUT, PATCH or DELETE requests, changes will be automatically and safely saved to db.json using lowdb. You can use JSON Server to serve your HTML, JS and CSS, simply create a ./public directory or use --static to set a different static files directory. There are many ways to set up SSL in development. One simple way is to use hotel. -

normalizr
Normalizes nested JSON according to a schema
Many APIs, public or not, return JSON data that has deeply nested objects. Using data in this kind of structure is often very difficult for JavaScript applications, especially those using Flux or Redux. Normalizr is a small, but powerful utility for taking JSON with a schema definition and returning nested entities with their IDs, gathered in dictionaries. Normalizr is built for various environments. Normalizr was originally created by Dan Abramov. Since v3, it was completely rewritten and maintained by Paul Armstrong. It has also received much help, enthusiasm, and contributions from community members. -

Native JSON Benchmark
C/C++ JSON parser/generator benchmark
Native JSON Benchmark is a benchmark suite for comparing C and C++ JSON parser and generator libraries. It evaluates both conformance and performance, which helps avoid treating speed as meaningful when a library does not parse or generate JSON correctly. The benchmark measures areas such as parsing speed, generation speed, memory use, and code size across many open-source libraries. It includes test data and JSON standard checks so implementations can be compared under more consistent conditions. The project is useful for library authors, C++ developers, and performance-focused engineers choosing a JSON implementation. Its main value is providing a transparent reference point for understanding tradeoffs among native JSON libraries. -

Serialize JavaScript
Serialize JavaScript to a superset of JSON
Serialize JavaScript to a superset of JSON that includes regular expressions, dates and functions. The code in this package began its life as an internal module to express-state. To expand its usefulness, it now lives as serialize-javascript — an independent package on npm. A primary feature of this package is to serialize code to a string of literal JavaScript which can be embedded in an HTML document by adding it as the contents of the script element. In order to make this safe, HTML characters and JavaScript line terminators are escaped automatically. -

Winterfell
Generate complex, validated and extendable JSON-based forms in React
Generate complex, validated, and extendable JSON-based forms in React. Winterfell allows you to build up complex, multi-page forms with conditional questions, validation, and conditional-page switching via a JSON schema, rendered by React. Winterfell was initially made for a project in a sector that required a large, complex form with questions that would result in more questions or different pages when you clicked next. With an easy-to-write schema and a high level of customization, comes great power. -

json-forms
JSON Schema to HTML form generator, supporting dynamic subschemas
JSON Schema to HTML form generator, supporting dynamic subschemas (on-the-fly resolution). Extensible and customizable library with zero dependencies. Bootstrap add-ons provided. This library supports dynamic schemas, that is, subschemas that can change depending on the value of other parts of the data. This allows the creation of dynamic forms that vary their shape depending on the values entered by the user. This is extremely useful for big autogenerated schemas, that aggregate lots of subschemas and have functional bindings, given that it allows to show the user a simpler, non-error-prone form, also avoiding asking for unneeded data. -

DefiantJS
Provides the ability for you to build smart templates applications
Do you need to query large JSON structures? Do you end up coding loops to parse the JSON and identify the data that matches your query? Defiant offers a better way. Defiant extends the global JSON object with a "search" method that enables lightning-fast searches using XPath expressions. Try out the XPath Evaluator to get the idea. DefiantJS provides the ability for you to build smart templates applicable on JSON structures, based upon proven & standardized technologies such as XSLT and XPath. As of v2.0.0, Defiant can be utilized in the Node.js environment. Since there is no default support for XML technologies in Node, the library puppeteer is initiated to mimic the browser environment, with Defiant running. All methods called from Node is piped via Puppeteer. Even though, Defiant now can be used in the Node environment - utilizing Defiant in the browser is recommended. It all boils down to whether you want your servers to run thousands of searches for your clients. -

Himalaya
JavaScript HTML to JSON Parser
Parse HTML into JSON. Himalaya bundles well with Browersify and Webpack. Himalaya transforms HTML into JSON, that's it. Himalaya is synchronous and does not require any complicated callbacks. Himalaya does not cut corners and returns an accurate representation of the HTML supplied. To remove whitespace, post-process the JSON; check out an example script. Himalaya can include the start and end positions of nodes in the parse output. To enable this, you can pass parse the parseDefaults extended with includePositions: true. Himalaya provides a stringify method. The following example parses the HTML to JSON then parses the JSON back into HTML. -

JSON5
JSON5 — JSON for Humans
JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand (e.g. for config files). It is not intended to be used for machine-to-machine communication. JSON5 was started in 2012, and as of 2022, now gets >65M downloads/week, ranks in the top 0.1% of the most depended-upon packages on npm, and has been adopted by major projects like Chromium, Next.js, Babel, Retool, WebStorm, and more. It's also natively supported on Apple platforms like MacOS and iOS. Formally, the JSON5 Data Interchange Format is a superset of JSON (so valid JSON files will always be valid JSON5 files) that expands its syntax to include some productions from ECMAScript 5.1 (ES5). It's also a subset of ES5, so valid JSON5 files will always be valid ES5. This JavaScript library is a reference implementation for JSON5 parsing and serialization and is directly used in many of the popular projects mentioned above. -
